Wez, Did you try this patch? It'd be good if someone who had serialization performance issues can verify this significantly improves it. Andi At 01:10 PM 10/24/2004 +0200, Sascha Schumann wrote:

The specific case I had was serializing an array containing a whole bunch of arrays representing the data from tables in a database. I don't recall how many rows there were, but the serialized data was around 5 MB. This was on windows, and feels like realloc doing over-time, so a fix could be something as simple as tweaking the smart_str chunking code; start with a fair initial size and perhaps having it double the size on each realloc.
    The default values you find inside php_smart_str.h are tuned
    for efficient usage of the engine's allocator.  They are not
    tuned for huge real-world usage.
    The attached patch should change that for var.c.
